Implementing smart monitoring system and control at traffic junction

Abstract

This paper presents an intelligent traffic control system to pass emergency vehicles smoothly. Each ambulance/VIP vehicle is equipped with special RFID tag(placed at a strategic location), which makes it impossible to remove or destroy. The RFID reader which is one part of the circuit is placed at 100meters before, at the junction to read the RFID tags attached to the vehicle. If the read RFID-tag belongs to the stolen vehicle, then a message is sent using GSM SIM300 to the police control room. Also, when an ambulance/VIP vehicle is approaching the junction, it will communicate to the traffic controller in the junction to turn on the green light. For this activity Zig-Bee module and ARM controller are used for wireless communications between the ARM    and traffic controller (Raspberry Pi).
